Optimization Of CDMA Wireless Network

CDMA network communication system is the military anti-jamming communication system originated in 1980s. With the rapid development of communication technology, it went throughversion upgrades and technology evolution such asIS95, CDMA2000, 1X, and EVDO. Now CDMA is one of the three recognizedglobal mobile communication standards. As one of the three major international mainstream commercial communication systems, the number of CDMA network is huge and it keeps growing. Although it started late in China, it developed rapidly with its own advantages. By the end of 2013 the number of China Telecommunications CDMA users exceeded one hundred million.The continuous development of core technology standard of CDMA network, user base, and business needs rely heavily on the wireless access layer of CDMA system network. Network construction and routine maintenance alone can't meet the ever growing needs. How to improve the network's reliability and efficiency.How to maximize the economic return of existingnetwork resources. Wireless network optimization becomes the focus of carriers and users.This study focuses on wireless access technology in CDMA network. It uses as case studies typical challenges from my day-to-day work in China Telecom, such as network coverage, interference, delay, and etc. Itresearches the principle and key technology; establishes the network optimization modelfor the coverage assessment system, the capacity evaluation system, and the frequency evaluation system. It collectsand analyzes the actual parameters. Lastly itidentifies and evaluates optimization options that systematically improve the wireless access performance.The completion of this study will provide solutions for CDMA network optimization. By system review, structural analysis, and specific issues resolution, this study also provides ideas for systematic system upgrade and expansion.The content of this paper includes:the first chapter Current status and development of wireless network optimization.The second chapter 2. CDMA network principle, key technology, and application.The third chapter Wireless interface technology and wireless access process.The fourth chapter Wireless network optimization options.The fifth chapter Wireless network optimization,It includes survey, design, assessment, implementation, retest, and results evaluation.
